.3 Claims. (CI. 33-47) vide .improved means for adapting the use ofstandard front sights to telescope height rear sights; such means beingquickly removable to afford use of telescope sight.

An improved feature of this invention is found in the provision of anovel quickly attachable and detachable band and locator by the use ofwhich thefront sight may be mounted in proper aligned and elevatedposition for use with a telescope-height rear sight and which band andlocator may be used on a rifle equipped with a front sight dove-tailedgroove disposed transversely to the longitudinal axis of the barrel;such band having adjustable means for locking or securing it into properaligned position controlled by the locator therefor.

With the above and other objects in view, my invention consists in thenovel combination and construction of the parts and members shown inpreferred embodiment in the attached draw-- ing, described in thefollowing specification and particularly pointed out in the appendedclaims. In the drawing attached hereto and forming a part hereof:

Fig. 1 is a diagrammatic illustration of a side elevation of a rifleequipped with my improved adaptor block and telescope-height front andrear sights, a telescope sight being shown in dash lines; v

Fig. 2 is a side elevation of a front sight mounted telescope-height onmy improved adaptor block which is positioned on the barrel ramp;

Fig. 3 is a perspective view of the improved adaptor block;

Fig. 4 is a side elevation of my improved front sight retaining barrelband showing the improved adaptor block and front sight mounted thereon;

Fig. 5 is a vertical section taken on line 5-5 of Fig. 4.

Fig. 6 is a perspective view of the barrel band retaining locator. and

Fig. 7 is an end view of the combination shown in Fi 4.

Fig. 8 shows aside view of the end of a large rifle barrel equipped withmy improved telescopeheight barrel band having an upper raised in-'tegral portion 'adapted to receive a standard front sight fortelescope-height rear alignment which does not require the adaptor blockshown in Fig. 3; v

In the illustrations, l indicates a rifle having a barrel H which isprovided with a rear sight l2 of telescope-height as clearly shown inFig. 1 wherein a telescope sight I3 is indicated in dash lines having asighting axis l4 aligned with a front sight generally indicated bynumeral [5.

An enlarged view of the front sight l shown in Fig. 1 is. shown in Fig.2 wherein the rifle barrel H is provided with a ramp l6 having adovetailed recess l1 adapted ,to receive the dove-tail portions IS and19 of the adaptor block l8 preferably made of metal.

The upper face of the adaptor block I8 is also provided'with adove-tailed recess 20 which is adapted to receive and frictionallyretain the dove-tailed base 2| of the cylindrical front sight 22. WhileI have preferred to illustrate my invention with a barrel or cylindricaltype of front sight such as shown in Figs. 2 and 4, any other standardor suitable type of front sight may obviously be used.

Obviously, a detachable front sight such as shown in Figs. 2 and.4 maybe mounted directly on the ramp I6 but to provide simple and quicklyattachable and detachable means for elevating a front sight totelescope-height for use with telescope-height rear sight or with sightswhich are movable-to telescope-height, I provide the novel adaptor blockla.

'The adaptor block I8 is preferably made from a single piece of steeland, as shown, of general rectangular shape having a pair of oppositesides, as the top and bottom, formed respectively with a dove-tailrecess 20 and dove-tail portions IS and I9 The block [8 might obviouslybe made without the vertical recess 23 which divides the dove-tailedbase into the two portions IS and I9 so that the dove-tailed base wouldresemble the dove-tailed portion of the front sight, but to providemeans for more securely mounting the adaptor block i8 on ramp IS, theadaptor block is split partially by the vertical recess 23 the upper endof which is drilled to provide a cylindrical cross-channel iii) and oneend of the block I8 is provided with a horizontal cross reoess-Mextending partly into the body of the r block toward and to a spaceddistance from the cylindrical cross-channel 23 andthe oppositeend of theblock is drilled and threaded to receive a horizontally disposedsecuring member such as the screw 25.

It will now be readily apparent that when the adaptor block 18 isslidably inserted with its dove-tailed portions l9 and l9 into thedovetail ramp recess 1 1, a tightening movement of the screw 25 willforce its inner end to press against an inner face of the recessed blockportion I 8 to cause a slight spreading apart of the dove-tail portionsI 9 and 19 to thereby securely lock the adaptor block in the ramp recessII. This spreading of the portions I9 and l9 is facilitated by thehorizontal cross recess 24.

Another feature of my novel adaptor block l8 resides in the provision ofa locator which, as herein shown, consists of a screw 26 having a head26*, a portion of the inner face of which is adapted to engage the sideface of the ramp IE to control and limit the inward sliding insertion ofthe dove-tailed adaptor block into proper aligned position on the ramp.Obviously, the dove-tailed base of the adaptor block could be formedwith an integral portion to extend below the portion I 9 to thus form alocator but I prefer to use the screw 26.

In rifles which are not provided with the dovetailed ramp l6 such asshown in Fig. 2, such rifles may be adapted to the use of my improvedadaptor block and front sight by my improved barrel band 21 as shown inFigs. 4, 5, 6 and '7.

The barrel band 21 is readily attachable to the end of a rifle barreland consists of a substantially cylindrical body split at its lower sideand provided with spaced integral ears 28 one of which is threaded toreceive a tightening member such as screw 29 having a head 25! thetightening movement or. i h willfil wi es e 2Utoward one another to seng clamp the band 21 onto the rifle barrel.

The upper side of the band body is formed with a raised integral portion3| to provide for a dovetailed cross-recess 30 which is adapted toreceive and frictionally retain the front sight, (or the adaptor blockl8 therebetween, when required). for telescope-height mounting of suchfront sight.

For proper aligned positioning of the barrel band 21 on the rifle barrell l, I provide a locator 32 which is illustrated in Fig. 6 and alsoshown in Figs. 4 and 5.

The locator 32 consists of a metallic body formed with angularlydisposed opposite ends 33 adapted to interfit within a dove-tailed crossgroove 34 on the rifle barrel H.

The locator 32 is formed also with a longitudinal integral upstandingrib 35 which is adapted to be received within the longitudinallyextending recess 36 within the band portion 3| and for practicalpurposes the locator is mounted in the rifle barrel dove-tailed recessor groove 34 with a driving fit.

From the above description and attached drawing it will be noted that Ihave provided a novel adaptor block and barrel band which adapt riflesto the use of front sights with standard height or telescope-height rearsights, and which accessories permit quick and easy detachment of sameto afford use of telescope sight if so desired.

I claim:

1. An adaptor for firearm front sights adapted to be mounted on thefirearm barrel and including a tubular body, said tubular body beingsplit on its lower side andhaving a pair of spaced integral ears, meansfor drawing said ears toward one another to clampingly secure the bodyto the firearm barrel, a groove in the top of the firearm barreldisposed transversely to the longitudinal axis of the barrel bore, and alocator held integral portion extending above said longitudinal channelwith a transverse channel within the upper face thereof adapted toreceive sighting means.

2. The combination with a firearm barrel having a removably mountedfront sight supporting member, of locating means for said membercomprising a locator having a dovetail base adapted to be frictionallyinserted in a correspondingly shaped groove which is disposed in thebarrel transversely to the longitudinal axis of the barrel, said locatorhaving a rib adapted to be aligned with the longitudinal axis of therifle bore to properly locate said member to thereby afiord parallelalignment of the sight axis with that of the rifle bore, and a frontsight detachably mounted on said member in-sightingmlignmentnniths atelescope-height rear sight.

3. In a firearm front sight, an adaptor removably mounted on the firearmbarrel and including a tubular member adapted to be frictionallysupported on the firearm barrel, a locator for said member having a baseportion adapted for frictional insertion in a groove disposed on andtransversely of the firearm barrel, said locator having a rib thereon inalignment with the longitudinal axis of the barrel bore and with avertical line intersecting the centers of the barrel bore and thefirearm front and rear sights, said member having a recess adapted toembrace therein said rib and a second recess extending transversely tosaid first-mentioned recess, and a front sight adapted to befrictionally mounted in said second recess.
